To all whom it may concern: y

Be it known that I, HARRY HALL Huss, a citizen of the United States, resdin et Phil adelphia, in the county of Philadelgphia und State of Pennsylvanie, have invented a certain new end useful Improved Air and Vacuum Controllin Device, of which the following is u speciiication.

The present invention relates to an im rovement upon the air and vacuum controling device shown and described in United States Letters Patent No. 924,617, dated June 8, 1909 Installation ol the device manufactured under the nbove patent has demonstrated the pref-:ence ol certain disadvantugeous features, notably, dilliculty with the stuingbox arrangement, :1nd water of condensation sputtering at the valve opening. The princi )al object of the present invention is to replace the aforementioned device with an air and vacuum controller, possessed, commercially speaking, of more ellicient and reliable working parts, of more compact and more readily nccessihie parts und of Simplified and cheapened construe*- tion. Other and further objects of the pres en! invention reside in the providingr of genral details' of Construction and the comhination thereof with other :nl iuncts hereafter referred to.

The invention consists ol' the improveV described und finally claimed` The nature. characteristic features `and scoie of the invention will he more fully un erstood from the following description taken in connection with thi` accompanying drawings forming part hereof andin which:

Figure 1, is n view in side elevation of the air und vacuum control-ling device embodyin the invention,

"ign 2, is a plan view of the underside of the same, certain casing parts hcing removed,

Fig. 3, is u fragmentary view, principally in section, of the right hand side of Figs. l, and 2, Y

Fig. 4, is a view in cross-section taken upon the line 4 4 of Fig. 3, and

Fig. 5, is :1 similar view taken upon the line. 5-5 of Fig. 4.

In the physical embodiment of the invention illustrated in the drawings, 10, designates un elongated frame or hanger of cast iron. As shown in Fig. 5, this hunger is of companion part l2, bolts 13, bein `present for securing the parte together. e opposite end of the honger has formed integral therewith one part of a shell orhousing 14,

detachably` connected to which is a compunion part 15. Screws 16, 17, are present for securing the parts together. One of the shell parts, in the drawings, the lower shell, is provided with lu s 18, for accommodating the screws 17. llshis shell is adapted to house certain parts to'be presently described. The relatively broad, flat, top of the han er 10, has formed integral therewith, lateraqly disposed ears 19, a iertured for the passe e therethrough of olts for securing t e han er to Flaca. Clemped beneath the vertica rib o the han r 10, and in a. medial 4line therewith, Vby t e parts 11--12-13, is an elongatedl brass, expansion ltube 20, screw-threa et each end. .ls shown this tube is slightl inclined from the clam 1l-12, upwar ly toward the shell 14--1 for :L nrlpose to presently appear, the free end ci) wiich tube is supported within the U-sheped, slotted portion 2l, of the lower shell, sec tube 20, is attachment to the return pipe aE n so-ralled vapor-vacuum heating system, such as is disclosed in U. S. Letters Patent N0. 968,668, dated August 30, 1910. The end 23. of the tube 20, carries :t hollow castirig 24. which is contained within the shell` btw-1?, This costing 24, is of rcctullgnlnr configuration, isv vertical] disposed und is provided at one side an near its bese with e screw-threaded boss to accommodate the end 23, of the tube 20.- The outer wall of the casting has formed therein, at a point opposite tlg" expansion tube a v'alvempcning 25, see Fig. 3. `Extended from the bottom of the casting.r 24. to with in a short distance of the top thereof is n central partition 26, thus forming separate compartments, Q7. und 28. Compartment 427, has therein baffle plates 27', arranged at an angle and o positely dis oued as shown by dotted lines in Fig. 4, to orm a tor-tonus passage. The baille platos, preferably, nre formed integral with the compartment walls. ilingedly connected lo the outer WallP Fi.; l?. and 5. The end 22, of the lois 'regulated to prevent very vslight pressure of casting 24, is means for closing the valveopenin 23. A description will now be given of suoi means. Suspended in n. vertical manner from ears 29, on the casting, is :in erm 30. The mode of suspension is accomplished by oppositely disposed screws 31, the points of which center' in counter-sunk portions 32, of the arm 30. Lnternl adjustments of the arm may thus be readily cured und u very easy moving hinge joint provided. Loosely passing horizontally through the lower end of the urm is a pin 33, screw-threaded at one end and having fixed to its other end a metallic vertical diskvulve or flap 34, for closing the valve-opening 23. A nut 35nnd lock nut 36, cooperate with the screw-threaded cud of the pin 33, to retain the Hup 34, in Aroper position. In this connection it muy be stated thnt there is n. loose fit provided by this urrungenient, sec Fig. 3, so that the flap may readily adjust itself to any inequalities of the sent of the valve-opening 23. The rear of the crm 30, is provided with e boss 37, for :ibutting against an adjustahly mounted, cushioning. device 38, for maintaining in closed position the Hep valve and to prevent buckling of the controller artsduring an pension period. The evice 38,y embraces the following parts: Penetrating the outer wall ofzthe shell 14, and extended within the shellis an elongated `nut 39, a lock nut 40, being present to retain the nut in adjusted position. Passing horizontally through the nutilf), is e rod 41, the inner end-of which isprovidcd with e fixed Cep 42, and the outer end is screw-threaded lo receive a. knob br handleA-l, which is fixed thereto as by a screw 44, sce Fig` 3. lntcrposed between Vthe cup 42, and the end 45, of the nut 39, is a coiled spring 46. lly proper manipulation of the .handle 13, the distance between the cap 42, and arm 30, may be .rc eluted. Also tension of s ring 46, may ge shifting of rod 41, by in system.

. Ininstellat'ionthe operation of the above described 'air and vacuum controlling device is `esfollows: Air which is present in the system passes through expansion tube, being pushed by the vapor in the system, und escapes through vulve-o ening Q5, the lia'pvalve permittiidr of suoli escupe. Simultaneously, in expanding the costing 24, is moved outward so that the part 37, of the flap-valve arm :ibuts against the cap 42, of the cushionin,gt device :ind maintains in closed position the flap-vulve 34. thus confining vupor within the system. be noted that in order to prevent moisture or wutcrpf condensation reaching the. valve opening. vuporin the casting 34, is oeuf-cd to first advance away from und then toward said votre opening. As vapor ndvnuc.

vapor heats up the tube 20. and' In this connection, it is to away from the valve opening, the bafflles seperate the moisture from the vapor ,lend deflect the moisture or water of condensation tion beck to the expansion tube. The latter being inclined away from the casting the water of condensation the tube und inds its way to the boilerA Thus water snitterin at the valve opening is eliminate Shouigd for any reason, a. small quantity of witter of condensation esce e to the shell 15, it readily eva crates. ln t isy connection the vente 46, in t e shell permit of egress of air from the system, permit of air entering said shell and further provide means for ins ecting the flap valve during oieretion of the device end the inscrtion therethrough of proper implements for cleaning of ground surfaces of vulve and valve seat if necessary. .With the flap vulve closed, there is now confined within the system u full capacity of vapor, the heet units of which 1n trensn'iissiou to u. room being heated, cause condensing oi" the vupor, thus creating a vneuuin within the syslmn, the advantages ot' which are well known.
